Hyperledger blockchain

Hyperledger Aries
Hyperledger Fabric is an open-source platform for developing privacy-focused enterprise applications. It supports smart contracts, or “chaincodes”, written in public languages (Golang, JavaScript, Java, and others).
Modular design for connecting custom functionalities to the network.
Permission network assigns individual roles based on the node type.
Peer nodes can batch and process multiple transactions simultaneously.
Membership identity service manages user IDs and validates members.
Access control lists provide authorization for specific network operation.
Both businesses and the network can customize consensus protocols.

Hyperledger Sawtooth

  Hyperledger Sawtooth is an enterprise blockchain platform for building applications for public and private blockchain networks. The architecture allows for multiple transaction and consensus types’ existence on the same network.
Modular structure for building networks with custom policy and rules.
Separate permissions for different groups of network nodes.
Advanced parallel scheduling for running transactions in parallel flows.
Native business logic and smart contract-based VMs support.
Event system for creating and broadcasting events on the network.
Proof of Elapsed Time (PoET) consensus algorithm support.

Hyperledger Aries
Hyperledger Aries is a dedicated infrastructure for blockchain-enabled, peer-to-peer interactions. It provides a shared cryptographic storage for blockchain clients and a communications protocol for off-ledger interactions between those clients.
A dedicated layer for creating, signing, and reading blockchain transactions.
A secure cryptographic storage for verifiable credentials and other data.
An encrypted, p2p messaging system for off-ledger interactions.
Ready framework implementations (mobile wallet, verifiable credentials, etc.
Continuous interoperability testing of agents and agent frameworks.

Hyperledger Iroha Hyperledger Iroha is a DLT-based blockchain framework for identity management. With YAC consensus algorithm support, it guarantees high network performance along with low waiting time for transaction completion.
System allows creating and managing custom fungible assets.
Account classification depending on the domain where it registered.
Data sharing (such as transactions and KYC procedures) across the network.
Verification of user permissions to perform transactions and queries.
Validation of transaction and query business rules within the system.
For shared accounts, transaction multisig is required for execution.

Hyperledger Indy
Hyperledger Indy allows creating self-sovereign digital identities on a blockchain, interoperable across siloed entities — domains, applications, and others. It provides users with full control over their ID data, including its storing and sharing.
Platform for user-managed exchange of verifiable claims about identifiers.
Decentralized identifiers enable non-centralized, persistent digital identities.
Sensitive data broadcasting through cryptography-backed p2p connections.
Support for zero-knowledge proofs (ZKPs) preserving ID data leaks.
Compatibility with third-party distributed ledgers and their standards.
Dynamic detection of previously undefined claims through claim schemas.

Hyperledger Besu
Hyperledger Besu is an open-source framework based on Ethereum. Designed to work with an Ethereum public network and private networks, it provides comprehensive permission functionality for consortium usage.
Smart contracts manage the permissioned network infrastructure.
JSON-RPC calls ensure update permissions for authorized users.
Updated IBFT consensus algorithm for faster transaction handling.
On-chain markers for off-chain transactions prevent double spend.
Possibility to set multi-company access to shared private data.
Scalability ensured by top-tier Java, cloud, and Ethereum tools.
